SPRING-BOARD WAGON.

SPECIFICATION forming part of Letters Patent No. 295,635, dated March25, 1884.

Application filed November 1, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN C. F. HARRIS, of

Littleton, in the county of Grafton and State of New Hampshire, haveinvented a new and Improved Spring-Board \Vagon, of which the followingis a full, clear, and exact description.

My invention relates to improvements in spring-board wagons; and itconsists of a footboard mounted on the spring-board by springs moreyielding and having longer range of movement than the springboarditself, to protect the feet of the rider from the benumbing jar of thespring-board; and it also consists of a novel arrangement of springswith the seat,

to render its motion easier than the motions it is subject to whenpositively connected to the spring-board, all as hereinafter fullydescribed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improved springboard-wagon body witha part of the seat in section. Fig. 2 is a plan view with a part of theseat broken out; and Fig. 3 is a sectional elevation on line mm, Fig. 1,looking forward, and with the seat raised.

The spring-board A is connected at the middle, between the ends andunder the seat E, by the cleats a, bearer a, and clip-bolt aflwith thesemi-elliptic spring 13 extending along under the middle of thespring-board nearly from one axle to the other, and suspended from thespring-board near the axles by the shackles C, so that the springre-enforces the board along the middle with much greater supportingpowerthan the board possesses, which power is so graduated by the nature ofthe spring that greater resisting-power is developed in proportion asthe weight on the springboard is increased, thus preventing thespring-board from being overpressed and sagging, as such spring-boardsdo after short service.

shackles are to be constructed with broad and substantial wearing partsin the joints, and with broad attaching-p1ates c for substantialconnection with the spring-board.

To prevent the benumbing effect of the springboard A on the feet of therider when exposed to the short, sharp, and rapid shocks The.

of such boards, I propose to mount a footboard, G, on the springboard bythe elastic fiat springs g, as shown, said springs being arranged tohave sufficient flexibility and range to wholly overcome the strong andrapidshocks of the spring-board; and'to prevent the recurrence of theshocks of the spring-board by the foot-rest being over-pressed andforced down on the spring-board, I propose to apply one or more'rubbercushions, g, to the under side of the foot-rest.

For relieving the seat from the jars of the springboard as much aspossible, I hinge the seat to its support H at the front h, and arrangethe fiat steel Springs (1 under the middle of the seat, or thereabout,with rubber cushions b at the back, to soften the shocks when the seatis pressed down on the seat-supports D road. For the support of thesesprings d, I

make a rack consisting of side bars, (2, center cross-bar, (72", andspring -holding crossbars (1 and d, in which the springs are arrangedindependently and so as to be secured between the side bars by thecross-bars, and I mount this rack on the side of the back-support D ofthe seat by a strong bolt, d", and with stud-pins d, projecting from thesurface of support D under the rack, so as to prevent it from vibratingon the bolt in case the seat is pressed down with more weight on one endthan on the other. -I may fasten the springs d in the raclcfraine in anysuitable convenient manner.

At the sides of the seat-supports D, and in the proper location forprotection of the same from the wear of the front wheels when turningshort around, I propose to apply wearirons F, having an upper rib, f,and a lower one, f, adapted to fend off the wheels alike rubber cushionsI) above the seat-supports,

substantially as described.

3. The combination, with the hinged seat E, of springs (I, supported inthe frame, consisting of side bars, d, and cross-bars, as described,

and attached to seat-support D by bolt cl, substantially as specified.
